… There are many design considerations when putting this type of thing together, as they explain: “More than 40 sensors and hydraulic actuators form a local area network (LAN) for the exoskeleton and function much like a human nervous system. The sensors, including some that are embedded within the shoe pads, are constantly providing the central computer brain information so that it can adjust the load based upon what the human is doing. When it is turned on, the exoskeleton is constantly calculating what it needs to do to distribute the weight so little to no load is imposed on the wearer. “We are taking great pains to make this as practical and robust as possible for the wearer,” said Kazerooni. “Several engineers around the world are working on motorized exoskeletons that can enhance human strength, but we’ve advanced our design to the point where a ‘pilot’ could strap on the external metal frame and walk in figure eights around a room. No one else has done that.” One significant challenge for the researchers was to design a fuel-based power source and actuation system that would provide the energy needed for a long mission. The UC Berkeley researchers are using an engine that delivers hydraulic power for locomotion and electrical power for the computer. The engine provides the requisite energy needed to power the exoskeleton while affording the ease of refueling in the field. The current prototype allows a person to travel over flat terrain and slopes, but work on the exoskeleton is ongoing, with the focus turning to miniaturization of its components. The UC Berkeley engineers are also developing a quieter, more powerful engine, and a faster, more intelligent controller, that will enable the exoskeleton to carry loads up to 120 pounds within the next six months. In addition, the researchers are studying what it takes to enable pilots to run and jump with the exoskeleton legs. The engineers point out that while the exoskeleton does the heavy lifting, the human contributes to the balance. “The pilot is not ‘driving’ the exoskeleton,” said Kazerooni. “Instead, the control algorithms in the computer are constantly calculating how to move the exoskeleton so that it moves in concert with the human.” Click here to check out a video demonstration.

Intresting News! Seems like robotics is playing good.However there is one majot concern.How much Ai is embeded in that exoskeleton.Though it works with concern with human body conditions but what if it can take over the control and judge its own decisions?
Just a thought

Could that video have been any more dull? I kept waiting for the guy to slam dunk a safe or at least kick an 80 yard field goal with a VW Bus. I guess I will have to watch Aliens for that sort of inspiration. But, really, for as cool as the invention is, that video was a sleeper.
He reminds me of a Roomba. Have you considered adding that technology? A Roomba that can climb stairs. It’s genius. But instead you have him walk in circles, like one of those battery operated puppies in the display in front of Radio Shack. Why does no one ever seek my input?
The best part about that technology is the stealth factor. That’s a pretty quiet motor.
Can you wear that on airplane?
What happened to that guy? Why doesn’t he just lose weight if he can’t move very well. I bet he’d get a lot farther faster if he wasn’t wearing that backpack that just farts in different frequencies every two seconds. My grandpa used to walk around like that. He had the first portable iron lung. We could hear him coming days before he came over. We would unplug his lung until he turned blue and tried to mouth the words “help me”. Then we’d plug him back in. He couldn’t laugh about it..the lung wouldn’t allow that.
Look, I saw the TV show “The Six Million Dollar Man” years ago - what’s the big deal hear? The SMDM was way more refined and sophisticated. Steve Austin would be lol at this thing. Frankly, I am too! Oh yeah, Steve ’sounded’ way cooler too - nununun…..nunununn…. This thing sounds like a giant aquarium pump on the fritz!
So how big and heavy is the actual motor? If it takes robotic legs to simply carry the motor that drives the robotic legs, then what’s the point?
Moreover, if you also wanted or needed robotic arms, where would the motor go? Perhaps it could be fitted to the top of an oversized helmet, as long as you also were provided a neckbrace, ear protection, and the four legged walker that my great-grandmother used to use while in the nursing home. But still, it’s an undeniable technological leap forward towards a brighter future.
